Versions

Minolta made three optically different 1.4/50 lenses.

  1. The MC Rokkor 50mm 1:1.4 PG is the oldest one with the nicest built quality and very good image quality
  2. The MD Rokkor 50mm 1:1.4 with 55mm filter thread. It is 60gramms lighter than the MC and the close focusing distance decreased from 50cm to 45cm.  This page is about this lens.
  3. The MD (Rokkor) 50mm 1:1.4 with 49mm filter thread.

Build quality and handling

Builts quality is very good, only the name plate and aperture ring are made from plastic, the rest is made from metal.

All in all it is a rather small lens and it balances very well on the Sony a7. The original lens shade is made from plastics, has a decent size and isn’t too bulky. Because the front element is rather exposed I would recommend using it.

The focusing ring travels around 100° from 45cm to 1m and a further 60° to infinity. The focusing has just the right amount of resistance but it is a bit small (8mm) for my taste.

The aperture ring has half stops from f/2.0 to f/16 and no stop between f/1.4 and f/2.0.

Optical performance

These results are based on the use with a Sony Alpha 7.

Bokeh

Minolta MD 50mm 1:1.4 @f/1.4
f/1.4: rather defined outlines
Minolta MD 50mm 1:1.4 @f/2
f/2: still defined outline but noticeably less
Minolta MD 50mm 1:1.4 @f/2.8
f/2.8: much less defined outlines but visible hexagons

Alternatives

Minolta MC 1.2/58: Quite a bit smoother bokeh and 8, not just 6 aperture blades make it a superior lens when bokeh is important. Sharpness is similar, the 1.4/50 might be a tad better. It also costs about 6 times as much and is nearly 150g heavier.

Minolta MC 1.7/55Not as sharp at wider apertures but it has nicer bokeh and is a bit smaller.

Minolta MD 2/50Worse bokeh but it is sharp across most of the frame from f/2, very small and only weights half of the MC 1.4/50. This is reflected in the build quality though. It is also free of lateral CA and distortion which the 1.4/50 is not.

Zeiss C/Y Planar 1.4/50: The Planar has more effective coatings which results in a much better flare resistance and higher contrast at wider apertures. The Minolta is a lot cheaper though.

Canon nFD 1.4/50: The Canon is quite a bit sharper at f/1.4 and f/2 but  and it doesn’t feel nearly as solid. Price is similar.

Zeiss Loxia 2/50: A modern lens which is sharp across the frame from f/2 with high contrast and exif transmission. Bokeh is the only real weakness I found. Oh an the price of course.

Sony FE 1.8/55 ZA: The Sony is super sharp from f/1.8 and it has much smoother bokeh. Manual focus is a pain in the a** though and it is expensive.

Conclusion

A typical 1.4/50 lens: Rather soft wide open, good for portraits by f/2, excellent by f/2.8 but it needs to be stopped down to f/8 for landscapes.
